Boron carbide tiles are a type of ceramic armor designed to provide high levels of protection against various types of ballistic threats. They are typically used in body armor systems for military and law enforcement personnel, as well as in armored vehicles and aircraft. Boron carbide tiles are valued for their exceptional hardness, low density, and high strength-to-weight ratio.
Boron carbide tiles are often used in combination with other materials, such as Kevlar or Spectra, to create composite armor systems that offer even greater levels of protection. They are also used in structural applications that require high levels of wear resistance, such as cutting tools, nozzles, and grinding media.
Defense: Boron carbide tiles are used as armor plates in body armor, helicopters, and armored vehicles.
Nuclear industry: Due to its high neutron absorption, boron carbide tiles are used as a control rod in nuclear reactors.
Abrasives: Boron carbide tiles are used in grinding, lapping, and polishing applications due to their hardness and wear resistance.
Metalworking: Boron carbide tiles are used as dies and cutting tools for metalworking applications.
Aerospace: Boron carbide tiles are used in space shuttles and rocket engines due to their lightweight and high hardness.
Sports equipment: Boron carbide tiles are used in sports equipment such as skis and snowboards for their abrasion resistance.
Refractory materials: Boron carbide tiles are used in high-temperature applications as refractory materials.
